As with managed code, any errors that occur during execution of an MATLAB® function or during data conversion are signaled by a standard .NET exception.
Like any other .NET application, an application that calls a method generated by the MATLAB Compiler SDK™ product can handle errors by either:
Catching and handling the exception locally
Allowing the calling method to catch it
Here are examples for each way of handling errors.
In the GetPrimes
example the method itself
handles the exception.
public double[] GetPrimes(int n) { MWArray primes= null; MyPrimesClass myPrimesClass= null; try { myPrimesClass= new MyPrimesClass(); primes= myPrimesClass.myprimes((double)n); return (double[])(MWNumericArray)primes). ToVector(MWArrayComponent.Real); } catch (Exception ex) { Console.WriteLine("Exception: {0}", ex); return new double[0]; } }
In the next example, the method that calls myprimes
does
not catch the exception. Instead, its calling method (that is, the
method that calls the method that calls myprimes
)
handles the exception.
public double[] GetPrimes(int n) { MWArray primes= null; MyPrimesClass myPrimesClass= null; try { myPrimesClass= new MyPrimesClass(); primes= myPrimesClass.myprimes((double)n); return (double[])(MWNumericArray)primes). ToVector(MWArrayComponent.Real); } catch (Exception e) { throw; } }
